Question from the youth life groups:
Why do we bother to evangelize if God knows who will be saved and who will not be saved?
This question is akin to a previous post on why pray when God is all-knowing? God does indeed know who will be saved and who will not be saved. He is the one who decides. He is after all, sovereign. He has not left it to the whim of men. Some people think that salvation is the choice of man but if we read the Scriptures honestly, we will see that it is God who chooses. This way, he gets the glory for our salvation. For example in Ephesians 1 and in Romans 9:
Ephesians 1:4–6
[E]ven as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace...
Romans 9:15–16
For he says to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.” So then it depends not on human will or exertion, but on God, who has mercy.
In love he predestined us. For what purpose? For the praise of his glorious grace! When he chooses us to be saved, God is showing mercy and we get to glorify him. Remember now, no one deserves to be saved. If everyone single last person on earth was sent to hell, God will be fully justified. Everyone has a guilty verdict on him. (Romans 3:23). But in his mercy, God saves.
